By the end of the month e will release a 3.0.1 mainly bug fixes version. Next we will focus on MoSync 3.1 which indeed, doesn't have a release date for now but it will get one ;)
However, we do have regular nightly builds and you can track our progress in Jira (http://jira.mosync.com), of special interest for you being http://jira.mosync.com/browse/MOSYNC-2044. I don't expect this to be done this month (In-App purchase and catching-up with wp7 support will take most of our time), but April looks promising.
